Hallowed Ground Unique Map Music

I've searched everywhere for an MP3 of the music that plays when you're near a boss in the Hallowed Ground map and have found nothing :c I would really like for this map music to be added to the OST or at-least a download given for it. Maybe for halloween?

It's the same music that is used for Sarn Arena. It's in the downloadable soundtrack I believe.

Thanks :D that's exactly what I was looking for.
